Ropey looking, but still an upgrade?
 

Been thinking about getting some stiffer ARBs for my wagon, and found this place on ebay:
http://stores.ebay.co.uk/stevesubaruparts/?_dmd=1&_nkw=anti+roll+bar

There are a couple of items in there for front and rear ARBs but there's no detail about their sizes etc. I sent him a message to check that they weren't for a widetrack and he said not, but didn't say what diameter they actually are. Was there a difference between stock WRX and STi anti-roll bars? Can anyone tell what they are from the ropey pics?

If all they need is a cleanup and repaint, they might be worth a punt for £20-odd quid.

P.S. His entire reply to my query about the size and diameter:
"The off a sti not a wide track"

Wrx to sti sizes are the same I believe so no gain in that way

I'm not sure about that.

I thought the blob WRX was 17mm whereas the STi was 20mm.

Sorry just seen this is for newage!
Not sure on these

Just measured the ones I have on my 05 wrx wagon, which as far as I know are completely standard. My front ARB is 20 mm, the rear is 17 mm.

Makes sense.

Apologies, I only referred to the rears above!
